Except that the soname for most versions of Berkeley DB are *not* "db",
but "db-4.1" or "db-4.2".

This is non-standard ... the Berkeley DB install target does not do
this, and I don't believe and distributions ship the symlink.
BTW, also note that not everyone building software has the luxury of
root access on the build host ...

Well, it is easier for headers than for libraries.

This goes for any library that has been through a few major versions (ie
The point is that a number of distributions provide library packages (ie
libdb-4.2.so in libdb4.2, and libdb-4.3.so in libdb4.3 package)
seperately from development packages (which would normally contain the
symlink to the appropriate version of the library - but no in the case
of Berkeley DB - and the headers).
There are obvoius uses to having the library available, but not headers,
but no real use for the headers without the library.
Thus, IMHO, the headers are authoratative, not the library.
I'll use the workaround (setting ol_cv_db_db_4_dot_3) for the Mandriva
packages, but fixing the bug would be better.
It's time to realise that the presence of a library does not imply the
presence of the headers, the static development library, the samples,
the documentation etc etc etc that may have shipped in the original
